function Restore-DbaDatabase {
<#
.SYNOPSIS
Restores a SQL Server Database from a set of backup files
.DESCRIPTION
Upon being passed a list of potential backups files this command will scan the files, select those that contain SQL Server
backup sets. It will then filter those files down to a set that can perform the requested restore, checking that we have a
full restore chain to the point in time requested by the caller.
The function defaults to working on a remote instance. This means that all paths passed in must be relative to the remote instance.
XpDirTree will be used to perform the file scans
Various means can be used to pass in a list of files to be considered. The default is to non recursively scan the folder
passed in.
.PARAMETER SqlInstance
The target SQL Server instance or instances.
.PARAMETER SqlCredential
Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted.
.PARAMETER Path
Path to SQL Server backup files.
Paths passed in as strings will be scanned using the desired method, default is a non recursive folder scan
Accepts multiple paths separated by ','
Or it can consist of FileInfo objects, such as the output of Get-ChildItem or Get-Item. This allows you to work with
your own file structures as needed
.PARAMETER DatabaseName
Name to restore the database under.
Only works with a single database restore. If multiple database are found in the provided paths then we will exit
.PARAMETER DestinationDataDirectory
Path to restore the SQL Server backups to on the target instance.
If only this parameter is specified, then all database files (data and log) will be restored to this location
.PARAMETER DestinationLogDirectory
Path to restore the database log files to.
This parameter can only be specified alongside DestinationDataDirectory.
.PARAMETER DestinationFileStreamDirectory
Path to restore FileStream data to
This parameter can only be specified alongside DestinationDataDirectory
.PARAMETER RestoreTime
Specify a DateTime object to which you want the database restored to. Default is to the latest point available in the specified backups
.PARAMETER NoRecovery
Indicates if the databases should be recovered after last restore. Default is to recover
.PARAMETER WithReplace
Switch indicated is the restore is allowed to replace an existing database.
.PARAMETER XpDirTree
Switch that indicated file scanning should be performed by the SQL Server instance using xp_dirtree
This will scan recursively from the passed in path
You must have sysadmin role membership on the instance for this to work.
.PARAMETER OutputScriptOnly
Switch indicates that ONLY T-SQL scripts should be generated, no restore takes place
.PARAMETER VerifyOnly
Switch indicate that restore should be verified
.PARAMETER MaintenanceSolutionBackup
Switch to indicate the backup files are in a folder structure as created by Ola Hallengreen's maintenance scripts.
This switch enables a faster check for suitable backups. Other options require all files to be read first to ensure we have an anchoring full backup. Because we can rely on specific locations for backups performed with OlaHallengren's backup solution, we can rely on file locations.
.PARAMETER FileMapping
A hashtable that can be used to move specific files to a location.
`$FileMapping = @{'DataFile1'='c:\restoredfiles\Datafile1.mdf';'DataFile3'='d:\DataFile3.mdf'}`
And files not specified in the mapping will be restored to their original location
This Parameter is exclusive with DestinationDataDirectory
.PARAMETER IgnoreLogBackup
This switch tells the function to ignore transaction log backups. The process will restore to the latest full or differential backup point only
.PARAMETER UseDestinationDefaultDirectories
Switch that tells the restore to use the default Data and Log locations on the target server. If they don't exist, the function will try to create them
.PARAMETER ReuseSourceFolderStructure
By default, databases will be migrated to the destination Sql Server's default data and log directories. You can override this by specifying -ReuseSourceFolderStructure.
The same structure on the SOURCE will be kept exactly, so consider this if you're migrating between different versions and use part of Microsoft's default Sql structure (MSSql12.INSTANCE, etc)
*Note, to reuse destination folder structure, specify -WithReplace
.PARAMETER DestinationFilePrefix
This value will be prefixed to ALL restored files (log and data). This is just a simple string prefix. If you want to perform more complex rename operations then please use the FileMapping parameter
This will apply to all file move options, except for FileMapping
.PARAMETER DestinationFileSuffix
This value will be suffixed to ALL restored files (log and data). This is just a simple string suffix. If you want to perform more complex rename operations then please use the FileMapping parameter
This will apply to all file move options, except for FileMapping
.PARAMETER RestoredDatabaseNamePrefix
A string which will be prefixed to the start of the restore Database's Name
Useful if restoring a copy to the same sql server for testing.
.PARAMETER TrustDbBackupHistory
This switch can be used when piping the output of Get-DbaBackupHistory or Backup-DbaDatabase into this command.
It allows the user to say that they trust that the output from those commands is correct, and skips the file header read portion of the process. This means a faster process, but at the risk of not knowing till halfway through the restore that something is wrong with a file.
.PARAMETER MaxTransferSize
Parameter to set the unit of transfer. Values must be a multiple by 64kb
.PARAMETER Blocksize
Specifies the block size to use. Must be one of 0.5kb,1kb,2kb,4kb,8kb,16kb,32kb or 64kb
Can be specified in bytes
Refer to https://msdn.microsoft.com/en-us/library/ms178615.aspx for more detail
.PARAMETER BufferCount
Number of I/O buffers to use to perform the operation.
Refer to https://msdn.microsoft.com/en-us/library/ms178615.aspx for more detail
.PARAMETER XpNoRecurse
If specified, prevents the XpDirTree process from recursing (its default behaviour)
.PARAMETER DirectoryRecurse
If specified the specified directory will be recursed into
.PARAMETER Continue
If specified we will to attempt to recover more transaction log backups onto database(s) in Recovering or Standby states
.PARAMETER StandbyDirectory
If a directory is specified the database(s) will be restored into a standby state, with the standby file placed into this directory (which must exist, and be writable by the target Sql Server instance)
.PARAMETER AzureCredential
The name of the SQL Server credential to be used if restoring from an Azure hosted backup using Storage Access Keys
If a backup path beginning http is passed in and this parameter is not specified then if a credential with a name matching the URL
.PARAMETER ReplaceDbNameInFile
If switch set and occurrence of the original database's name in a data or log file will be replace with the name specified in the DatabaseName parameter
.PARAMETER Recover
If set will perform recovery on the indicated database
.PARAMETER AllowContinue
By default, Restore-DbaDatabase will stop restoring any databases if it comes across an error.
Use this switch to enable it to restore all databases without issues.
.PARAMETER GetBackupInformation
Passing a string value into this parameter will cause a global variable to be created holding the output of Get-DbaBackupInformation
.PARAMETER SelectBackupInformation
Passing a string value into this parameter will cause a global variable to be created holding the output of Select-DbaBackupInformation
.PARAMETER FormatBackupInformation
Passing a string value into this parameter will cause a global variable to be created holding the output of Format-DbaBackupInformation
.PARAMETER TestBackupInformation
Passing a string value into this parameter will cause a global variable to be created holding the output of Test-DbaBackupInformation
.PARAMETER StopAfterGetBackupInformation
Switch which will cause the function to exit after returning GetBackupInformation
.PARAMETER StopAfterSelectBackupInformation
Switch which will cause the function to exit after returning SelectBackupInformation
.PARAMETER StopAfterFormatBackupInformation
Switch which will cause the function to exit after returning FormatBackupInformation
.PARAMETER StopAfterTestBackupInformation
Switch which will cause the function to exit after returning TestBackupInformation
.PARAMETER StatementTimeOut
Timeout in minutes. Defaults to infinity (restores can take a while.)
.PARAMETER KeepCDC
Indicates whether CDC information should be restored as part of the database
.PARAMETER PageRestore
Passes in an object from Get-DbaSuspectPages containing suspect pages from a single database.
Setting this Parameter will cause an Online Page restore if the target Instance is Enterprise Edition, or offline if not.
This will involve taking a tail log backup, so you must check your restore chain once it has completed
.PARAMETER PageRestoreTailFolder
This parameter passes in a location for the tail log backup required for page level restore
.PARAMETER EnableException
By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
.PARAMETER Confirm
Prompts to confirm certain actions
.PARAMETER WhatIf
Shows what would happen if the command would execute, but does not actually perform the command

https://dbatools.io/Restore-DbaDatabase
.EXAMPLE
PS C:\> Restore-DbaDatabase -SqlInstance server1\instance1 -Path \\server2\backups
Scans all the backup files in \\server2\backups, filters them and restores the database to server1\instance1
.EXAMPLE
PS C:\> Restore-DbaDatabase -SqlInstance server1\instance1 -Path \\server2\backups -MaintenanceSolutionBackup -DestinationDataDirectory c:\restores
Scans all the backup files in \\server2\backups$ stored in an Ola Hallengren style folder structure,
filters them and restores the database to the c:\restores folder on server1\instance1
.EXAMPLE
PS C:\> Get-ChildItem c:\SQLbackups1\, \\server\sqlbackups2 | Restore-DbaDatabase -SqlInstance server1\instance1
Takes the provided files from multiple directories and restores them on server1\instance1
.EXAMPLE
PS C:\> $RestoreTime = Get-Date('11:19 23/12/2016')
PS C:\> Restore-DbaDatabase -SqlInstance server1\instance1 -Path \\server2\backups -MaintenanceSolutionBackup -DestinationDataDirectory c:\restores -RestoreTime $RestoreTime
Scans all the backup files in \\server2\backups stored in an Ola Hallengren style folder structure,
filters them and restores the database to the c:\restores folder on server1\instance1 up to 11:19 23/12/2016
.EXAMPLE
PS C:\> $result = Restore-DbaDatabase -SqlInstance server1\instance1 -Path \\server2\backups -DestinationDataDirectory c:\restores -OutputScriptOnly
PS C:\> $result | Select-Object -ExpandProperty Tsql | Out-File -Filepath c:\scripts\restore.sql
Scans all the backup files in \\server2\backups stored in an Ola Hallengren style folder structure,
filters them and generate the T-SQL Scripts to restore the database to the latest point in time,
and then stores the output in a file for later retrieval
.EXAMPLE
PS C:\> Restore-DbaDatabase -SqlInstance server1\instance1 -Path c:\backups -DestinationDataDirectory c:\DataFiles -DestinationLogDirectory c:\LogFile
Scans all the files in c:\backups and then restores them onto the SQL Server Instance server1\instance1, placing data files
c:\DataFiles and all the log files into c:\LogFiles
.EXAMPLE
PS C:\> Restore-DbaDatabase -SqlInstance server1\instance1 -Path http://demo.blob.core.windows.net/backups/dbbackup.bak -AzureCredential MyAzureCredential
Will restore the backup held at http://demo.blob.core.windows.net/backups/dbbackup.bak to server1\instance1. The connection to Azure will be made using the
credential MyAzureCredential held on instance Server1\instance1
.EXAMPLE
PS C:\> Restore-DbaDatabase -SqlInstance server1\instance1 -Path http://demo.blob.core.windows.net/backups/dbbackup.bak
Will attempt to restore the backups from http://demo.blob.core.windows.net/backups/dbbackup.bak if a SAS credential with the name http://demo.blob.core.windows.net/backups exists on server1\instance1
.EXAMPLE
PS C:\> $File = Get-ChildItem c:\backups, \\server1\backups -recurse
PS C:\> $File | Restore-DbaDatabase -SqlInstance Server1\Instance -UseDestinationDefaultDirectories
This will take all of the files found under the folders c:\backups and \\server1\backups, and pipeline them into
Restore-DbaDatabase. Restore-DbaDatabase will then scan all of the files, and restore all of the databases included
to the latest point in time covered by their backups. All data and log files will be moved to the default SQL Server
folder for those file types as defined on the target instance.
.EXAMPLE
PS C:\> $files = Get-ChildItem C:\dbatools\db1
PS C:\> $files | Restore-DbaDatabase -SqlInstance server\instance1 `
>> -DestinationFilePrefix prefix -DatabaseName Restored `
>> -RestoreTime (get-date "14:58:30 22/05/2017") `
>> -NoRecovery -WithReplace -StandbyDirectory C:\dbatools\standby
>>
PS C:\> #It's in standby so we can peek at it
PS C:\> Invoke-DbaQuery -SQLInstance server\instance1 -Query "select top 1 * from Restored.dbo.steps order by dt desc"
PS C:\> #Not quite there so let's roll on a bit:
PS C:\> $files | Restore-DbaDatabase -SqlInstance server\instance1 `
>> -DestinationFilePrefix prefix -DatabaseName Restored `
>> -continue -WithReplace -RestoreTime (get-date "15:09:30 22/05/2017") `
>> -StandbyDirectory C:\dbatools\standby
>>
PS C:\> Invoke-DbaQuery -SQLInstance server\instance1 -Query "select top 1 * from restored.dbo.steps order by dt desc"
PS C:\> Restore-DbaDatabase -SqlInstance server\instance1 -DestinationFilePrefix prefix -DatabaseName Restored -Continue -WithReplace
In this example we step through the backup files held in c:\dbatools\db1 folder.
First we restore the database to a point in time in standby mode. This means we can check some details in the databases
We then roll it on a further 9 minutes to perform some more checks
And finally we continue by rolling it all the way forward to the latest point in the backup.
At each step, only the log files needed to roll the database forward are restored.
.EXAMPLE
PS C:\> Restore-DbaDatabase -SqlInstance server\instance1 -Path c:\backups -DatabaseName example1 -NoRecovery
PS C:\> Restore-DbaDatabase -SqlInstance server\instance1 -Recover -DatabaseName example1
In this example we restore example1 database with no recovery, and then the second call is to set the database to recovery.
.EXAMPLE
PS C:\> Get-DbaBackupHistory - SqlInstance server\instance1 -Database ProdFinance -Last | Restore-DbaDatabase -PageRestore
PS C:\> $SuspectPage -PageRestoreTailFolder c:\temp -TrustDbBackupHistory -AllowContinues
Gets a list of Suspect Pages using Get-DbaSuspectPage. The uses Get-DbaBackupHistory and Restore-DbaDatabase to perform a restore of the suspect pages and bring them up to date
If server\instance1 is Enterprise edition this will be done online, if not it will be performed offline
AllowContinue is required to make sure we cope with existing files
.EXAMPLE
PS C:\> $BackupHistory = Get-DbaBackupInformation -SqlInstance sql2005 -Path \\backups\sql2000\ProdDb
PS C:\> $BackupHistory | Restore-DbaDatabase -SqlInstance sql2000 -TrustDbBackupHistory
Due to SQL Server 2000 not returning all the backup headers we cannot restore directly. As this is an issues with the SQL engine all we can offer is the following workaround
This will use a SQL Server instance > 2000 to read the headers, and then pass them in to Restore-DbaDatabase as a BackupHistory object.
.EXAMPLE
PS C:\> Restore-DbaDatabase -SqlInstance server1\instance1 -Path "C:\Temp\devops_prod_full.bak" -DatabaseName "DevOps_DEV" -ReplaceDbNameInFile
PS C:\> Rename-DbaDatabase -SqlInstance server1\instance1 -Database "DevOps_DEV" -LogicalName "<DBN>_<FT>"
This will restore the database from the "C:\Temp\devops_prod_full.bak" file, with the new name "DevOps_DEV" and store the different physical files with the new name. It will use the system default configured data and log locations.
After the restore the logical names of the database files will be renamed with the "DevOps_DEV_ROWS" for MDF/NDF and "DevOps_DEV_LOG" for LDF
.EXAMPLE
PS C:\> $FileStructure = @{
>> 'database_data' = 'C:\Data\database_data.mdf'
>> 'database_log' = 'C:\Log\database_log.ldf'
>> }
>>
PS C:\> Restore-DbaDatabase -SqlInstance server1 -Path \\ServerName\ShareName\File -DatabaseName database -FileMapping $FileStructure
Restores 'database' to 'server1' and moves the files to new locations. The format for the $FileStructure HashTable is the file logical name as the Key, and the new location as the Value.
